I installed a pyro in the driver's side manifold, is that a good place for accurate readings? I got a max reading today on some hills in 90* heat of 1250... Right at the limit I know, but with the A/C on and music holding 65 wasn't bad for a 22 year old motor ;p. Anyways, I got off the highway, andstopped at a stoplight and the truck started to stutter like it was low on fuel and sucking air. Did it last night at the local fastfood joint too. Checked and the tank was 3/4 the way full. Okay, so I bump the idle speed up a bit waiting and it kind of went away. I think I was sucking air somewhere, but it has NEVER done this Up the hill after the stoplight it just held 35, so I clicked on the hazards and narrowly avoided being run down by GMC, and pulled off. Idled on the shoulder for a minute and everything was normal. Coming down from the mountains last night, I also noticed a ticking noise that varied linearly with engine speed, if that helps at all... Sorry for the long post....
